Overview
What this challenge is about.
Chunking Strategy Bake-Off for Financial Filings. Intermediate challenge in analysis. Analyzing real datasets and building models that drive decisions, earn ...
The Brief
What you'll do, and what you'll demonstrate.
Compare 4 chunking strategies on a 10-K research assistant and recommend one that lifts numerical-question accuracy without regressing on narrative.
This is not a data exercise. It is the work an analyst does when stakeholders need answers from messy data. That distinction matters to every hiring manager who has seen candidates describe statistical methods and none who have extracted insight from messy, real-world data.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Implement and compare 4 chunking strategies on real documents
- Design a fair evaluation that separates narrative and numerical questions
- Reason about chunking trade-offs (granularity, table preservation, embedding quality)
- Document the recommendation for a non-research engineering team
